NEW YORK, Dec 19 (Reuters) - Global equity markets edged higher on Wednesday after a three-day sell-off which had investors seeking safety in bonds due to mounting pessimism over world economic growth.

Crude oil futures have plummeted almost 10 percent since last Thursday while world stock markets have tumbled to 19-month lows.

Investors expected the U.S. Federal Reserve to announce one more interest rate hike at a policy meeting later in the day, but they speculated that the U.S. central bank might signal that it plans to stop tightening monetary policy.

MSCI's index of stocks around the globe rose 0.7 percent, boosted by broad gains in Europe and the U.S., though it remains down nearly 12 percent since the start of December.

On Wall Street, the Dow Jones Industrial Average rose 169.77 points, or 0.72 percent, to 23,845.41, the S&P 500 gained 19.45 points, or 0.76 percent, to 2,565.61 and the Nasdaq Composite added 61.22 points, or 0.9 percent, to 6,845.13.

The latest jolt on the growth front came from Japan, which said its export growth slowed to a crawl in November, an ominous signal for the trade-focused economy.

Logistics and delivery firm FedEx, considered a bellwether for the world economy, slashed 2019 forecasts, noting "ongoing deceleration" in global growth.

"It's a confluence of several important factors: the market is adjusting its outlook on growth and there is a consensus we will see a slowdown. More importantly, the market is adjusting to the idea this will translate into lower earnings growth," said Norman Villamin, chief investment officer for private banking at Union Bancaire Privee in Zurich.

"It's being complicated by the tightening liquidity situation with the Fed expected to move today and the ECB having signaled the end of its (stimulus)".

Expectations of a Fed pause and the equity sell-off have sent 10-year Treasury yields to their lowest since August. Benchmark 10-year notes last rose 2/32 in price to yield 2.8156 percent, from 2.823 percent late on Tuesday.

Yields in Japan and Australia also reached multi-month lows.

The dollar index fell 0.49 percent, with the euro up 0.57 percent to $1.1426.
